Silicon Labs buys ZigBee module maker Telegesis

November 25, 2015 // By Graham Prophet
Silicon Labs has announced the acquisition of Telegesis, a supplier of wireless mesh networking modules based on Silicon Labs' ZigBee technology. The move, says Silicon Labs, “accelerates [the] company's roadmap for ZigBee and Thread-ready modules and ... IoT mesh networking.”

A privately held company founded in 1998 and based near London (High Wycombe, UK), Telegesis is a ZigBee specialist with presence in the smart energy market, providing ZigBee module solutions to many of the world's top smart metering manufacturers.

This acquisition strengthens Silicon Labs' ability to support customer needs with comprehensive mesh networking solutions ranging from wireless system-on-chip devices to plug-and-play modules backed by 802.15.4 software stacks and development tools. Telegesis modules integrate the antenna and provide a pre-certified RF design that reduces certification costs, compliance efforts and time to market. Designers can migrate later from modules to cost-efficient SoC-based designs with minimal system redesign and full software reuse.

Telegesis exclusively uses Silicon Labs' ZigBee technology in its module products, which are deployed in smart meters, USB adapters and gateways for smart energy applications. Additional target applications include home automation, connected lighting, security and industrial automation. The modules come with Silicon Labs' EmberZNet PRO ZigBee protocol stack. Telegesis also offers comprehensive development and evaluation kits to help developers streamline their ZigBee-based applications.

Silicon Labs completed the acquisition of Telegesis on November 20, 2015, for a cash purchase price of approximately $20 million, with approximately 20 Telegesis employees transferring to Silicon Labs.
